Abstract: In some aspects, a magnetic gear system includes a flux focusing magnet arrangement having a low-pole count rotor, a pair of modulator rotors disposed on either side of the low-pole count rotor, and a pair of high-pole count outer rotors disposed outside of the pair of modulator rotors. In some aspects, a magnetic gear system includes a motor with a stator and a pair of low-pole count rotors disposed on either side of the stator. The magnetic gear system further includes a pair of modulator rotors disposed on either side of the motor, and a pair of high-pole outer rotors disposed on opposite sides of the pair of modulator rotors.

Abstract: A hover-capable aircraft includes a body including a tubular strut, a first rotor assembly rotatably coupled to the body and positioned about the strut, wherein the first rotor assembly includes a first plurality of circumferentially-spaced blades, a first actuation assembly including a first plurality of electronically controlled actuators coupled to a first swashplate and configured to control the movement of the first swashplate relative to the body, and a control system coupled to the body and configured to control the first plurality of actuators, wherein the control system includes a cable extending through a passage formed in the tubular strut and in signal communication with the first plurality of actuators.
